To all whom it may concern:

Be it known that we, HERBERT E. Gnu nnn'r and PHILIP REINHARDT, both citizens of the United States, and residents, respectively, of the borough of Manhattan, city, county, and State of New York, and of the borough of Brooklyn, city of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Flooring Compositions, of which the following is a specification. I

The particular object of our invention is a flooring composition capable of production in the form of tiles or which can be laid as a single piece of covering of any desired shape and size and which is fire-resistant, sanitary, dustl ess, light, is not liable to crack, warp or chip, which is extremely durable, which possesses a resiliency tothe tread and which exhibits an adhesive or nonslipping tendency to the shoes of the pedesrian.

In the production of floorings of this class, it has been found that those compositions which possess the'property of required hardness for continued use are liable to crack and chip, due to the settling of the flooring and to other causes and are extremely heavy, causing an excessive weight pressure upon the structure, and further that they have little or no resiliency and hence are tiring to the pedestrian, and on account of their slippery or smooth surface present a possible cause of danger.

\Ve have found that all of these disadvantages may be overcome by the use ot a-proper base carrying ground'or finely divided cork.

It is essential that the base have such properties as will fit it for the successful application of the uses to which it is applied as aflooring'surfaceand at the same time allow of the proper mixture with and retention therein of the finely divided cork.

Among the compositions suitable for this purpose we have found that the oxy-chlorid cements are particularly well adapted and that the value of such mixture is enhanced if silex be used as a body-giving compound and asbestos fiber be introduced to give the mixture elasticity to prevent cracking and to soften the flooring to the tread. The addition of cork to a composition of this char- Specification of Letters Patent.

ping surface.

As an example of a flooring composition of our invention we give the following: calcined magnesite 75 pounds, asbestos fiber 10 pounds, silex 12 pounds, finely divided cork :25; pounds, color 8 pounds. These ingredients are thoroughly mixed any known means and shortly prior to application. the mixture is made into a paste of the required consistency by adding magnesium chlorid solution 20 B. This pasty mass is then spread over the area to be covered and allowed toset, and rubbed down and polished in the ordinary manner.

\Ve have found that superior results may be obtained with reduced time and labor if the mass be allowed to set into a semi-hard condition, then scraped and ground until the particles of cork are exposed, after which it is allowed to take its final setting. It is then waxed andpolished to a smooth finish. e

Other silicious substances may be substi tuted for the silex. The addition of color isinto cement, or other binding means, entire area to be covered.

N e do not limit ourselves to the' particular materials, quantities or order of their incorporation given above, all of which may be varied without going beyond the scope of our invention as described and claimed.

hat is claimed, is: As a new article of manufacture, a flooring composition produced by adding a solution of magnesium chlorid to a mixture of j 75 pounds maguesite, 10 pounds asbestos fiber, 12 pounds silex, 25 pounds finely divided-cork and 8 pounds color.
